别克LesabreFuel Filter Replacement at your home or office.

When to consider replacing the fuel filter:

• 定期维修.The most common reason to change the fuel filter — your vehicle’s maintenance schedule may specify a filter change interval.
• 燃料污染。If any foreign fluids, bad fuel, or water enters into the fuel system mistakenly, the fuel filter should be replaced.
• 燃油系统维修。如果已更换燃油泵，则在汽油箱中或在汽油箱中进行了工作，或者已经清洁或更换了燃油喷油器，请始终安装新的燃油滤清器。重大的发动机维修或更换发动机也需要新的过滤器。
• 泄漏。There should be zero leakage of fuel, whether liquid or vapor, in the fuel system. Leaks at the fuel filter connections might necessitate not only a new fuel filter but also new O-rings in the push-on connections to the fuel filter.
• Warning light indication.如果燃油滤清器中积累了过多的水，则柴油动力车辆可以配备水传感器警告光电路，以发出信号。水将必须排干，过滤器可能要维修或更换。
